【摘要】 介绍了一台基于多缝单丝法的强流离子束发射度仪,讨论了缝丝法的测量原理及该发射度仪的系统构成和设计要点,给出了利用该发射度仪对中国原子能科学研究院ECR离子源发射度的测量结果。对于强流离子束,只能采用短缝对束流进行不完全采样以实现充分的冷却。由此引起的系统误差,可以通过模拟计算估计其修正值。
【Abstract】 A high-current ion beam emittance measurement unit (EMU) is introduced inthe paper. The measurement principle of slit-wire method is discussed. The system con-struction and design key-points of the EMU are discussed, too. The measurement re-sults of emittance of ECR proton source at China Institute of Atomic Energy using theEMU were given. For high-current ion beam, short slits have to be used to sample partof beam so that effective cooling could be performed, which would introduce some sys-tematic errors and its correction could be estimated by simulation.
